CNN —Around 2,500 endangered seals have been found dead on Russia’s Caspian coast, state-run news agency RIA Novosti reported Sunday, citing authorities in the North Caucasus region.
Caspian seals, the only mammals found in the Caspian Sea, have been classified as endangered on the International Union for Conservation of Nature (IUCN) red list since 2008.
According to RIA, inspectors were patrolling the coastline in search of additional dead seals.
Meanwhile, specialists from the Caspian Environmental Center were analyzing samples from the dead seals to identify the cause of death.
The mass deaths come after more than 140 Caspian seals were found dead on Kazakh beaches of the Caspian Sea earlier this year, according to KASPIKA, an agency for the conservation of Caspian seals.
